适应性普遍流是位于现实世界中的动态工作流，它修改其执行以适应执行环境的变化。一方面，这要求流程必须具有上下文感知能力，另一方面，它必须足够灵活，以允许轻松且持续的适应。在本文中，我们提出了一组用于将适应逻辑嵌入到流规范中的构造和原则。此外，我们还展示了如何扩展 Web 流程建模 (BPEL) 标准语言以支持所提出的内置适应结构。
Adaptable pervasive flows are dynamic workflows situated in the real world that modify their execution in order to adapt to changes in the execution environment. This requires on the one hand that a flow must be context-aware and on the other hand that it must be flexible enough to allow an easy and continuous adaptation. In this paper we propose a set of constructs and principles for embedding the adaptation logic within the specification of a flow. Moreover, we show how a standard language for web process modeling (BPEL) can be extended to support the proposed built-in adaptation constructs.
